  • Finished product diagram and installation dimension diagram of new energy intelligent monitoring device
Most wind and photovoltaic box transformers are located in harsh outdoor environments, with significant temperature differences throughout the year. High temperatures can reach over 60 ℃, while low temperatures may reach below -40 ℃. Wind power plants on the ocean also need to consider the corrosion, condensation, and high temperature effects of salt mist gases. Recently, temperature controllers used in wind and photovoltaic box type transformers to measure oil temperature are mostly transformer oil surface temperature sensors used in ordinary environments. The normal temperature range of these products is -30 ℃ to 50 ℃, and they will not have any problems in normal usage environments. However, when used in photovoltaic box transformers, they cannot meet the needs of the usage environment.
Our company specializes in developing temperature and humidity sensor monitoring and control products. The new energy intelligent monitoring device is an intelligent instrument designed specifically for the field of modern new energy technology. It can measure the oil temperature of transformers and the temperature and humidity inside the box transformer. It uses a digital tube to display the temperature and humidity values, which is intuitive and clear; Automatically start the fan when the ambient temperature is too high; When the oil temperature is too high, functions such as over temperature alarm output, over temperature trip output, etc; When the humidity in the transformer environment is too high, the environmental fan or heater will be automatically started for dehumidification to ensure a good operating environment for the equipment. The sensor adopts armored oil liquid sensor with long lead wire. Display humidity without distortion, without the need for humidity compensation and calibration. The temperature adopts high-end sensors, which have good consistency and repeatability, high accuracy, high stability, and strong anti-interference ability. With humidity trip record query and RS485 communication (or 4-20mA current output) function. The product does not lose data when powered off.
Provide PT100 output for transformer oil temperature; Provide temperature signals of 4-20mA output from transformer oil temperature and environmental temperature and humidity sensors; Provide RS485 communication interface.
